Abstract

The problem of the study lies in two directions. The first one is the depletion of fossil energy, which translates into raising the prices of electrical power despite its scarcity in desert areas and new cities. The second is obtaining a sustainable energy source that ensures the efficiency of raising water from the wells during the irrigation period. The study included an evaluation of the performance of six wells in the Wadi El-Natroun region, Beheira Governorate, Egypt, divided into three systems for supplying the energy needed to raise water during the operating period wells, namely Petrol Power (PPS), PV power (PVS), and Hybrid Energy Sources (HES). Data for water well characteristics and initial operating tests were collected from private companies. The evaluation criteria included average discharge and rate of discharge during the test period, hourly and daily discharge rate, and efficiency during the operation period. The study concluded that the average water discharge (AD) for the hybrid system recorded the highest values than that the PPS and PV systems per the interference time of operation. The highest dynamic water level (15.68m) is found at the PPS system of 33.1 min testing time. But, the lowest (8.78m) is found at the HES system under the same times and vice versa with drawdown level decreases.
